Abstract

See full text

In its presently preferred form, an endotracheal tube (ET) is shaped to bring its rounded or bevelled distal tip end into the central axis or midline, for ease of passage into the glottic opening and through the region of the vocal cords; the distal-end shaping also involves a laterally and vertically reducing taper that is symmetrical with respect to a vertical plane of symmetry which includes the central axis. Distal-end ports or perforations are in the symmetrically arrayed walls of a triangular section of the tube which at least characterizes the region of tapering section and which conforms with the triangular-shaped space between the vocal cords, for added ease of insertion into the patient's trachea. The reducing taper of the roughly triangular-shaped section extends preferably and optionally to form a wedging fit against vocal cords, with or without the assistance of a conventional inflatable cuff of similar sectional profile.
